In recent years, preparation and separation applications of gamma-alumina membranes have been extensively studied. In catalysis research field, this membrane can be used not only as a separating medium but also as a catalyst or catalyst support. In this paper, a gamma-alumina catalytic membrane was prepared by a sol-gel technique, then special attention was paid to its surface properties related to catalysis, its surface acidity, hydroxyl, microstructure and pore properties was studied by IR with pyridine adsorption, XRD and N{sub 2} adsorption at low temperature, 1-butanol dehydration as a probe reaction was used to study its reaction property.
